HOOK-AND-EYE TAPE.

Specification of Letters Patent.

Patented July 3o, 191e.-

Application led March 22, 1917. Serial No. 156,711.

To all whom t may concern.'

Be it known that I, ERWIN KRAMER, a

citizen of the United States, residing at Carlstadt, in the county ofBergen and State of New Jersey, have invented certain new and usefulImprovements in Hook-and-Eye Tapes, of which the following is aspecification.

My invention relates to hook and eye tapes in which a laminated strip offabric has a plurality of hooks or eyes secured between the layers withthe operative parts exposed beyond one edge thereof and it is my objectto produce a strong, simple,` neat hook and eye tape the manufacture ofwhich will be free from all complications.

In the drawing Figure 1 is a face view of my improved tape with thefacin layer torn away at one end; Fig. 2 a bac view with' the base layertorn away at one end; and Fig. 3 a sectional view of the tape. Fig. 4 isanv enlarged detail perspective view of the tape with the base stripflattened out and the facing strip turned up at right angles thereto, tomore clearly illustrate the manner of stitching, and also the locationof the perforations in the line of stitching.

Fig. 5 is a cross sectional view on the line 5--5 of Fi 4 showing howthe stitching secures, the acing and base fabrics together.

Fig. 6 is a view similar to Fig. 5 taken on the line 6 6 of Fig. 4 andshowing how the stitching'is confined wholly t0 the facing fabric atpoints where perforations occur in the base.

Fig. 7 is a perspective View somewhat similar to Fig. 4 showing thefacing fabric turned down, and illustrating the position of theperforations (in dotted lines) with reference, to the stitching.

Fig. 8 is a view of the tape after it has been folded along the line ofstitching, and also showing how the fastener (in dotted lines) passesbetween the folded-back edge of the base and the facing strip.

The im roved hook and eye tape consists of a base fabric 1, and afacingv fabric 2, one edge of the latter being secured to the former bya line of stitching 3 at a point back from the edge of said base equalto thewidth of the facing strip, thus producing, even when the strip isin a flat condition as shown in Fig. 7, a continuous marginal pocket Pfor completely concealing and protecting the anchor ends of the hooksand eyes as will presently appear. As shown in the drawings, this basestrip may be folded back upon itself along the line of the said stitchin3, merely for the purpose of facilitating t e application of the tapestrip to a garment, since the stitching of the base and facing togetheras shown provides the necessary double-leaf housing for the anchor endsof the hooks.

At uniform intervals corresponding to the hook and eye spacing-aperforation or slit 4 is made in the base fabric in the line of thestitching 3, which perforation may be, and. preferably is, made at thetime of stitching by an intermittently operated perforating device onthe sewing machine. This line of stitching 3 therefore passes throughand secures the base and facingfabrics together except at the pointswhere the base fabric has been perforated or slitted, thus leavingopenings in the base along the line of the said stitching 3 whereby the`latter at these points is confined wholly to the facing fabric as shownon Fig 6. The stitching 3 is therefore, straight ahead sewing and theopenings, properly spaced, are automatically provided for without theuse of jump or tying stitches'.

And, furthermore by locating these per foratons or slits ldirectly inthe line of the stitching 3, the latter imparts a substantialreinforcing effect to the tape at the points where the hooks or eyes arelocated thus enabling the same to withstand a maximum pulling stress inthe zone of each fastener.

The eyes 5 or hooks 6 .are inserted in the marginal pocket P between oneedge of the base strip 1 and the facing strip 2 with their shankportions projectin through the openings provided between t e facing andbase at polnts where the slits 4 occur and across the line of thestitching 3 when the tape is in the flat condition shown in Fig. 7 or,when said tape is folded along the line of stitching as shown in Figs.1, 2, and 3, the operative portions of the hooks or eyes project beyondthe edge of the tape. In its marketable form the tape is in thecondition shown in Fig. 7 of the drawings but, as previously indicated,when it is desired to apply the same to a garment it is folded along theline of stitching as clearly illustrated in Figs. 1, 2, and 3.

Figs. 4 to 8 inclusive of the drawings clearly illustrate the locationof the perforations or slits 4 in the line of stitching 3. Figs. 5 and 6show how the stitching 3 of the base and the lower side of the foldedfin edge of the facing fabric, whereby when the fabric is folded alongthe line of stitching 3 as shown in Figs. Sand 8, the shank of thefastener may project through the opening thus formed and not through theperforation, while the raw edges of the said perforation or slit areexposed as clearly shown in enlarged form in Fig. 8.

This construction not only provides a very reliable carrier for thehooks and eyes, but at the same time produces an exceptionally strongfand durable tape since the line of .stitching is continuous andunbroken..

A hook or eye tape consisting of a base 20 fabric, a facing fabric,stitching securing the latter fabric to the former at va point back fromthe edge thereof to provide a continuous marginal pocket, andperforations formed in the base directly in the line of stitching. 25

In testimony whereof I have affixed my signature in the presence of twowitnesses.
